The patients will be assessed for pain during rest and coughing/activity immediately after the surgery, every 15 minutes for first 2 hrs and 6 hourly thereafter until 24 hours after the removal of epidural or block catheters. Patients whose VRS scores are higher than 5/10 in PACU, apart from getting a bolus in the epidural or PVB may also receive IV Hydromorphone 0.2 mg every 5 minutes till pain subsides to a score of 3/10. Nausea will be documented using a categorical scale (none, mild, moderate and severe), pruritus scores will be recorded every 12 hours (categorical scale, none, mild, moderate and severe). Time to onset of bowel sounds, time to first flatus and time to first bowel movement would also be recorded with time 0 being the arrival time in PACU. Post-operative hemodynamic changes, blood pressure and urine output will be documented every 6 hours. Duration of significant hypotension will be computed from the nursing chart, significant hypotension being systolic BP less than 90 mm Hg. Patient satisfaction will be documented on a visual analogue scale where 0 is totally dissatisfied and 100 is totally satisfied. Adverse events such as local anesthetic toxicity, wound infection, dehiscence, urinary retention, cognitive dysfunction and neurological deficits will be prospectively collected. The failure rate of both the techniques and the number of attempts will also be recorded.
